Specification of Letters PatentNo. 10,289, dated November 29, 1853.

T all whom t may concern:

Be it known that JOSHUA HEILMANN, of the Republic lof France, did inventcertain new and useful machinery for combing wool and other ,fibrous substances by removing therefrom all the short fibers and such foreign substances as may be mingled therewith; and I do hereby declare the following to'be a full, clear, and exact description thereof, reference being had in the accompanying drawing, in which- Plate I, shows the several views of the machine, and Plate II represents sect-ions illustrating the progress of thel wool through the machine, and the various positions of I its parts.

To clearly understand the invention, it may be well to trace, first, the fiber through its various stages of progress, and then afterward follow out the parts of the ma chine by which their motions were made.

Commencing the operation at Plate II, position 1st, it will be observed that the wool, represented by red lines, lies along between two series of bars, B, B, placed sufiiciently far apart to readily admit the sliver of wool between them; in this position there is a portion of the sliver hanging down beyond the plate or jawv C, uponwhich the bars B slide, as will hereafter appear; `and the'upper jaw D, being held down `firmly in contact with jaw C, the sliver hanging beyond them is in position ready to be combed; this operation is effected by aseries of teeth z', z', z', projecting from a large cylinder M, which revolves just below. When the teeth i, have removed all the foreign substances, as well as the short fibers,

the cylinder M, continues around till it passes the position shown in ilo. 2, 3, 4, and 5, and arrives at the position 6, where a projecting segment H, of cylinder M, passes under the ends of the combed fibers, during which time the comb-teeth Agwhich in position l were between the -bars B, and run through the sliver of wool between the two series, has been lifted out, as clearly shown. in positionQ, and the bars slide back, as.

shown in position 3,`without carrying the sliver with it;when clear back from the jaws, as seen in positionY i,cthe comb Ai again enters between the bars B, and piercing thesliver in a new place, holds it fast; andthen the jaw D rises and loosens its .grasp upon the fiber, as shown at position 5, where, as before remarked, the segment H has been brought under the fiber'Q; this segment is Ysmooth and covered with leather, like the rollers of a ldrawing frame; during the progress of the parts above named to the position (3, two rollers F. G, which run in contact, rise together, andlat the position' 6, the upper roller F, which is grooved, has a short forwardmovement around G, so as to bring it inV contact with the surface of the segment H, by which the ends ofthe liber are pinched between said segment and roller; thus situated, the segment continues its rotary motion, and by theconta'ct turns the rollers F, andG, with it, anddiaws the ends of the fibers of wool 'between them; a single comb E, at this instant is thrust through the sliver Q, close to the jaw D, at y;

the precise point where the fibersy were pinched in the jaws; in thisstate the roller moves away from the segment H, Vwhich' passes around, leaving the rollers to fall, ,c

downto their lowest depression. Having entirely drawn out the fibers from the sliver, this small portion of fibers Q, then hangs of the fiber Q, which have .not been combed, are struck by the succeeding segfiber which has been ybrought down 'between i the jaws C and D, by the barsV B sliding Yforward 0n plate Ctoward D, when the parts assume the'first position again, andv `thenext portion of fiber is vgrasped vand combed by the samev set of. teeth, which finish afterward the preceding portion of A .fiber that had been previously` taken from the jaws by the rollers. The s'econdportion ofy fibers drawn between the rollers F, G,

are united with the rst, and as the process y is continued, a sliver of long fibers of w00] is formed, and passes off throughcondensing rollers, shown inl Plate I, Fig.f1.4` In this last named figure,"(which isa vertical Vsection of the machine) is 'n represented a y, i

.brush N, below ther cylinder, which revolves Y with rapidity in the contrary direction to Y cylinderV M, Vand cleans off vthe short fibers or ,iioil combed from the longfibers, these short bers are then taken from the brush N by' a doifer P,r from whichthey'are re-k moved in a sliverby a comb R, worked in the ordinary way, and the sliver descends into a boX below. l

" `The machinerybywhichcthefseveral n'ion 1' ioo" v 80' down, and as the rollers again rise, the ends Y beyond this segment the drum is open, there j being a space between the segment and the next succeeding comb.` The lower part C of the jaws, that feeds the wool to the comb on the cylinder, is attachedto the ends of` two curved arms V(7c3) centering on a shaft (o) above the cylinder, just described, one

of'which arms (k3) Vis shown in Fig. l; this arm` is loose on shaft (0'), and is drawn down by a spring (742) into the position shown in Fig.4 l, where itis arrested by a stationary stop affixed to the frame; on the same shaft (0) as a center, are two other arms of like form, one on each side of the frame, and projecting on the sideV oppo site to the arms (7a3) and suspend on their ends a jaw D, which is made to cut against the jaws C in the following way: The arms (791) are firmly aflixed to shaftr(0),xand turn with it; there is also upon the same shaft, an arm (Ict), see Fig.f2, that Aterminates in a segment piece (165) which has a long curved slot in it, in which there is a wrist pin fastened, and adjusted to any point in the slot; this pin has a connecting rod (Z1) connecting it with a crank on the shaft (su), which is turned by means of the train of gear wheels from the prime mover, or band wheel on shaft (s), clearly delineated in Fig. 2; the result of the movement thus effected, is to. cause the jaw D, to descend till it comes in contact' with the jaw C, gripping the fiber that is between them; after which it presses baclrV the jaw C a certain distance; and then on its return it is accompanied by C tillit arrives at the point before named, shown at Fig. l; and then by moving alittle farther, recedes from C, and the jaws are opened, as is also shown in the same figure; this movement is lrepeated at each semirevolution of the drum on shaft (01).

B, beforefnamed, lying upon the lower jaw C, are required to slide up Vand down upon it; this is effected in the following way: A shaft (817V) is suspended in bearings in the arms (7c3) directly underwthe' jaw C; near either endlof-V this shaft an arm[("v1) is affixed, forked at t-he end as shown in F ig;

i2; a pin lies inthe fork of this lever, thatis connected with `the bars above, so that It will be perceived that the series of bars in' either direction, the4 bars (B, slide uip and down, as the case may be; to cause the .shaft (sw) to rotate, and at the Sametime allow it to follow the movements of"t`hejaw C, with which it is connected by the arms (7c3) on which it is suspended, an arm (/v) is affixed to the shaft (81V) Aand stands out in a nearly horizontal posit-ion; a long slot is made in its end, in which a'pin is fastened that can be set to vvary the movement; said pin attaches a connecting rod (u) with the lever (o), which connects with `the upper end of a long lever (y1 y) this `is in two parts, so as to be set ata greater or less the bars, and in addition thereto, withdrawing its teeth from between the bars, and a gainV thrusting them forward between them at proper intervals; to accomplish this, a long arm A projects downward .from the comb A, on either side, and `a similar one, B', is affixed tothe bars B; these arms are jointed together at (01V), as shown bythe dotted lines, Fig; 2; a rod T, fastened-at (0H) stationaryV point, extends forward to the j back of Vthe 'comb and is attached to it, so

that when the jaw C, and bars B, are thrust back, the comb `teeth are drawn out, but the combV rises and falls with the lbars.

Then the jaw C, and bars B, return to their state of rest, as shown in Fig; ,1, the comb lA,'returns between the bars.` These movements are all required to properly present and comb the/first halfof Aan aggregation of fibers, after which they areseizedV between i l two rollers, F, and G, the construction and Voperation ofwhich are as follows: Two stout curved levers, (a), onevon each `side of the frame, have their fulcrum on shaft (0. fv),

and curving forward and upward, bear the j,

rollers F, Gf on ,their upper ends; these rollers do not have their'bearings in the arms (a), but in levers L", attached thereto by a pivot or rule joint; the arms (s) are forced Vupward at ,their forward ends by means `ofa weight suspended to a. projection back of the shaft, and the two rollers F, Gr,

- are kept pressed togetherlby the same weight,

throughvthe intervention of a bent lever (2') connectinggrod` (zf anda second bent lever j, l `(.z"), `and hook rod (zw) hooked on to the roller journal F, all of whichV actequally upon therollers, whatever may be the position of the'arms (z).` The lever L jointed i to the end of arm (a) Vhasa bifurcated hook at its outer end, in which the T-shaped headY when the shaft (81V) is made tol turn a little'l of the rod (zx) rests, the lower end of said rod being att-ached to a lever (evi), having its fulcrum at shaft (evi), a spiral spring (am) is coiled around the rod (ex), its lower end resting against a set screw, by which its tension is regulated, and its upper end bears up against the under side of lever (LX). The arm (evi) is moved up and down by a grooved face-cam (a) on the shaft (S) which makes two revolutions for one ofthe drum M on shaft (0) the operation effected by raising the arm (evi) is to allow arm to rise with it, till the rollers F, G, have attained a proper height, when thev arm (e) isarrested by a stop (8") on the frame, but the arm (evi) continues upward, which, by means of the spring (am), raises the end of the lever (LX) and turns inward the roller F, against the segment H of the drum, with a force of contact sutlicient to cause segment H, to turn it, and the roller G, so as to pinch and draw in between them the ends of the fiber in the manner before set forth, when the arm (evi) again descending first brings down the lever LX, removing thus the roller F from Contact with segment H, and then descending farther, draws down the arm (e), rollers and all, to their lowest point of depression, by which the half combed fibers are drawn from the sliver between the jaws; before, however, the rollers begin to descend and draw out the fibers, a comb E, with a single row of teeth descends through the sliver, close up to the point where the jaw D has pinched it, and remains there till the fibers are separated; its motion is made by a cam (aa) on the shaft (5) which strikes against a stud roller on the lower end of an arm J, aflixed to a shaft (0") on which shaft are also affixed two long curved arms J to the ends of which the comb E, is afxed.

The brush, doer, and comb have been before described; the shafts are all turned by gearing or bands from the main shaft (s),

see Fig. 2; on the further end of which is a spur wheel (w) gearing into an other (10) l y sides a stud wheel ('wvi), that communicates motion to shaft (8),which revolves at the same rate as shaft (s).

The brush N is driven by a band B, running from a small pulley on its shaft on to a drum on the shaft (s) the crank shaft of the comb runs with the brush, and the dofer receives a slow motion from a worm wheel, working into a gear on its shaft; said worm wheel being on the upper end of an inclosed shaft (s) driven by bevel gear from shaft s Y f Having thus fully described the machine for combing wool, what I claim therein as new, and .for which I desire to secure Letters Patent, is-

l. The segment drum M, constructed and arranged substantially as herein described.

2. I claim the aws C, and D, for gripping and presenting the wool properly to the combs, to be combed; and 1n connectlon therewith the bars B, and comb A, kfor delivering the wool. 3. I claim the rollers F, and G, or their equivalent, for seizing and retaining the wool as it is combed, and forming it into a continuous sliver, substantially as described.
